HOISTING AND LOADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 377,183, dated January31,1888.

Application filed September 19, 19.87. Serial No. 250,072. (No model.)

To aZZ 1072 0772 it may concern.-

Be it known that I, DAVID S. WHITE, of

l the city of Minneapolis, in the county of I-Iennepin and State ofMinnesota, have invented certain Improvements in Hoisting and LoadingMachines, of which the following is a specitic-ation.

My invention relates particularly to improvements in machines designedespecially for use in forming excavations for sewers and other purposes;and the objects I havein view are to provide a machine by means of whichthehoisting-bnc'kets maybe raised and brought over a suitable hopper orreceptacle and its contents discharged into said receptacle, and all bya single direct pull upon the rope or chain which supports thehoisting-bucket.

Other objects of the invention will appear from the following detaileddescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is an end elevation of my improved machine, showing theparts in the position that they assume as the bucket is being lowered orwhile it is being raised and before it strikes the device thatautomatically directs its contents into the hopper or receptacle. Fig. 2is a similar view, but partially in section, showing the device inposition for discharging the contents of the bucket into the hopper orreceptacle.

In the drawings, 2 represents a suitable carriage which may be of anysize and construction and is mounted upon suitable wheels. This carriageis preferably adapted to permit a car, 3, to be passed under it,and thehopper and receptacle-5 is mounted upon the carriage and is adapted todump its contents into the car 3 when it is beneath the carriage. I makeno claim, however,in this application to the carriage or car, as hereinshown, as I have claimed the same in a separate application for LettersPatent filed on the 3d day of May,l887, Serial No. 236,920.

Pivoted upon the frame of the machine is a suitable arm or bar, 7,having its upper end pivoted to the side of the receiver 9, that is openat both ends andis adapted to receive the hoisting-bucket 11, ashereinafter described. Two other bars, 13, similar to each other, arealso pivoted upon the carriage at their lower ends,and their oppositeends are pivoted to the receiver 9 at a point below the pivotal point ofthe bar 7. The other ends ofthe bar 13 are secured to the carriage at apoint nearerits center than the pivotal point ofthe bar 7, so that thebars 7 and 13 when in the position shown in Fig. 1 are in the form of anirregular letter X. The receiver 9 is open at both ends,and its lowerend is preferably flared,so as to form a guide for the hoistingbucket.To the top of the receiver is secured a suitable standard, 15, in whichare mounted the sheaves 17.and 19. A hoisting rope or chain, 21, passesover the bucket 1l,through the receiver 9 between the sheaves 17 and 19,and over the sheave 19 and over the sheave 23,mounted in the suitablestandard, 25,at or near the opposite side of the carriage. A rope maythen be carried to a winding-frame or other device by which it may bewound up and released for the purpose of hoisting or lowering thebucket. The bars 7 and 13 areso proportioned to each other and to thereceiver that the receiver preferably stands substantially vertical whenin its normalposition, as shown in Fig. 1. I

prefer, however, to provide the bar 7 with a supporting-bar, 29, againstwhich the side of the receiver bears when in a vertical position. Themanner of operatlng the devlce is as follows: Power being applied to therope 21 to raise the bucket 11, it is hoisted vertically until it hasentered the receiver 9. A convenient projection upon the bucket 11-suchas a projecting flange at the bottomencounters the lower end of thereceiver, and a pull on the rope, continuing, causes the receiver to bemoved with the bucket. The bars 7 and 13 are thereby turned upon theirpivots, and at the same time the receiver is also turned on the pivotalsupports between it and these bars. A continued movement of the ropecarries the bar 13 into a substantially vertical position, as shown inFig. 2, and brings the re ceiver over the receptacle 5 on the carriagein an inverted position. The material in the bucket 11 will then fallout and into the receptacle 5. In order that all of the material may inall cases be directed from the receiver into the receptacle 5, I preferin some instances to provide a chute, 33, that is pivoted upon the pivotthat secures the upper end of the bar 7 ICO to the receiver 9. The lowerend of this chute rests upon a guide-bar, 35, secured to the bar 13. Asthe receiver is moved toward the receptacle 5, the lower end of thechute 33 is raised by the guide-bar 35 and brought into proper positionover the receptacle 5, when the bar 13 stands in a vertical position. Imay also provide a connecting rod or link, 37, pivoted to the upper endof the bar 7 and to the axis of the sheave 19. The chute 33 and itsguidebar may, if preferred, be omitted, as the material will be directedinto the receptacle 5 without the use thereof. 7 v

I do not confine myself to the details of construction herein described,as the same may be substantially varied without departing from theprinciples of my invention. The form of the receiver and the form of thebucket may be varied; and while I have shown a receiver consisting of aclose cylinder, it need not be in this form and need not be close,except where it is desired that the receiver shall also act as a chuteto guide the material from the bucket into the receptacle in thecarriage. The parts, however, might be proportioned so that the bucketwould be brought directly over the receptacle or receiver, and it isalso preferably provided at its lower end with a weight, 41, that may besecured thereto in any suitable manner for the purpose of causing thereceiver to tip backward and resume its normal position as soon as thestrain on the rope is relieved.

I do not confine myself to the use of a carriage or movable frame-work,as the device may be permanently attached to any foundation, in

which case the portion 2 would represent the sill to which the hoistingapparatus is attached.

I claim asmy invention-- 1. The combination,with a suitable carriage orframe and a receptacle mounted thereon, of the receiver 9,.bars 7,pivoted to the frame and to said receiver at a point near its upper end,and the bars 13, pivoted to the receiver at a point near its lower end,and also pivoted to said frame, the hoisting bucket and rope,substantially as described.

2. The combination, in a machine of the class described, with a suitablecarriage, of a standard secured upon the carriage, a receiver,'9, amovable support secured upon said carriageandsupportingsaidreceiver,ahoisting-bucket, and a rope or chain passingthrough said receiver and over said support, substantially as described.

3. The combination,with a suitable carriage having a standard securedtherein, and with a sheave or pulley on said standard, of a movablesupport adapted to overhang the side of the carriage, a receiver, 9,carried by said support, a receptacle on said carriage between saidstandard and said support, a hoisting-bucket, and hoisting-rope passingover said support and over the sheave on said standard, substantiall yas described.

In testimony whereof I have hereunto set my hand this 14th day ofSeptember, A. D. 1887.

DAVID S. WHITE.
